Beagle - that's why I didn't go into the Victor SR2 MRR profile. Same radar as yours, I believe, and all it could do was classify "Small, Medium or Large" targets from, as you say, high level. Searchwater much more capable, but I'll say no more.
BTW I was also one of your "Kamikaze Canberra Pilots" - wonderful fun provided you didn't take it seriously!
